Chiller Evacuation | Pin Hole Leak vs Moisture Plateau
AVRPV in action… the two Chiller vacuums below both look like great finishing results:
· Left (yellow) → 171 microns
· Right (green) → 145 microns
But what happens over time tells the real story:
At 3 hours
· Left: +101 micron rise
· Right: +104 micron rise
At 6 hours
· Left: +184 micron rise
· Right: +138 micron rise
At 9 hours
· Left: +254 micron rise
· Right: +146 micron rise
🔎 Diagnosis:
· Left (yellow) → pin hole leak = straight line
· Right (green) → moisture boiling = plateauing line
📌 Knowledge:
Standard practice says a 24-hour standing vacuum is best.
But trending vacuums detail critical data patterns and tell us more than just the endpoint.
